3、Structural advantages of Insulation annealing furnace

The Insulation annealing furnace has the following structure

1. Radiation chamber

The heat load of the main place for Insulation annealing furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.

2. ventilation system

Ensure the gas flow in the furnace and maintain the stability of the atmosphere and temperature in the furnace.

3. combustor

The device that mixes natural gas with combustion-supporting air and ejects it is the core component of the heating furnace.

4. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

5. convection chamber

The material is heated by convection heat transfer of high temperature flue gas discharged from the radiation chamber. Flue gas washes the tube wall of the furnace tube at a high speed to carry out effective convection heat transfer, and its heat load accounts for about 20%-30% of the whole furnace. The convection chamber is generally arranged above the radiation chamber, and some are placed on the ground alone. In order to improve the heat transfer effect, nail head tubes or finned tubes are often used in furnace tubes.

4、Introduction of advantages of Insulation annealing furnace

Insulation annealing furnaces have the following advantages.

1. Rapid temperature rise

The Insulation annealing furnace can heat the metal material to the required temperature in a short time, which improves the production efficiency.

2. Wide application range

The Insulation annealing furnace is suitable for forging and heating of various metal materials, including steel, aluminum and copper. At the same time, it can also be used in metal heat treatment, tempering and other technological processes.

3. Reduce operating costs

The efficient combustion and waste heat recovery system of the Insulation annealing furnace can significantly reduce energy consumption, thus reducing operating costs.

4. Improve product quality

Because the Insulation annealing furnace can realize uniform heating and precise control, it is helpful to improve the product quality and yield of metal materials.

5. Extend the service life of equipment

The Insulation annealing furnace adopts advanced combustion technology and materials, which has a long service life and low maintenance cost.

5、Insulation annealing furnace function

Insulation annealing furnacemultifunctional, with functions such as hardening and tempering, Forging heating, Casting heating, heat treatment and normalizing，at the start of the operation,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.。

6、Insulation annealing furnace principle

Insulation annealing furnacein the course of work,Heat of combustion based on fuel. Natural gas is sprayed from the burner, mixed with combustion-supporting air and burned to produce high-temperature flame and smoke. These high-temperature flames and smoke transfer heat to the metal materials in the furnace by radiation and convection, so that they gradually heat up to the temperature required for forging.，is a common Insulation annealing furnace，it is widely used in war industry, heat treatment, war industry, light industry and Machinery manufacturing，the product looks beautiful.，it is an ideal choice for customers to buy Insulation annealing furnace。
